Geography of Uttarakhand + Disaster Management | Prelims: GLOF, Chamoli district, Wadia Institute of Himalayan Geology (Dehradun).
Context
A 22-scientist team led by the Wadia Institute of Himalayan Geology began installing an automated early-warning system (EWS) at the high-risk glacial lake Vasundhara Tal in Chamoli on 29 September 2026; the work window runs till 15 October 2026.
Key facts
Sensors track water level, weather, snow depth, sub-surface temperature, ground movement and water flow; data travels via satellite due to poor mobile connectivity.
Partners: CSIR-CBRI Roorkee, USDMA, the National GLOF Risk Mitigation Programme, SDRF, NDRF and ITBP.
Uttarakhand has 344 glacial lakes (2023 assessment), of which 13 are high-risk; Vasundhara Tal is one of them.
A lesson from the 2013 Kedarnath and 2021 Chamoli (Rishiganga) disasters, both linked to glacial/high-altitude hazards.
Way forward
Extend EWS to all 13 high-risk lakes, link sirens to downstream villages, run community drills and feed data to the State Emergency Operations Centre.
Concept
GLOF (Glacial Lake Outburst Flood) = sudden release of water when a moraine or ice dam fails, often triggered by avalanches, landslides, earthquakes or heavy rain. Risk is rising with glacier retreat due to warming.
Flowchart of the Vasundhara Tal GLOF early-warning chain: sensors at the lake, satellite link, data centre and USDMA, alert to district and sirens in downstream villages, followed by evacuation by SDRF, NDRF and ITBP. — StudyForGS

SBM-U 2.0 (2021) targets garbage-free cities and used-water management. Pirul (Chir pine needles) is highly inflammable and a key forest-fire driver; the state buys it under 'Pirul Lao–Paise Pao'.
6. Rajya Sabha polls on 16 October: Uttarakhand's lone vacancy as Naresh Bansal's term ends; BJP finalising nominee
Indian Polity — Parliament | Prelims: Article 80, Fourth Schedule, open ballot, Uttarakhand's seats in Parliament.
Context
The Election Commission has announced biennial polls to 11 Rajya Sabha seats — 10 in Uttar Pradesh and 1 in Uttarakhand — with voting on 16 October 2026. The Uttarakhand seat falls vacant as Naresh Bansal's term ends; the state BJP has sent a panel of contenders to its central leadership.
Key facts
Uttarakhand has 3 Rajya Sabha and 5 Lok Sabha seats; its 70-member Assembly forms the electoral college.
Members are elected by elected MLAs through proportional representation by single transferable vote (STV).
Open ballot for RS polls was introduced in 2003 by amending the RP Act, 1951.
Term is 6 years; about one-third of members retire every 2 years (Art. 83(1)).
Way forward
Hill-state concerns such as migration, disasters and border villages need a strong voice in the Council of States, which represents federal interests.
Concept
Article 80: maximum strength 250 (238 elected + 12 nominated); state-wise seats in the Fourth Schedule. Rajya Sabha is a permanent body, not subject to dissolution.
7. UPSC turns 100: PM releases commemorative coin, stamp and '100 Landmark Judgements' book at Bharat Mandapam
Constitutional bodies | Prelims: Articles 315–323, Lee Commission, GoI Act 1935, removal of members (Art. 317).
Context
On 1 October 2026, the Union Public Service Commission completed 100 years; the Prime Minister attended the centenary celebrations at Bharat Mandapam, New Delhi, ending a year-long observance that began on 1 October 2025.
Key facts
Public Service Commission set up on 1 October 1926 on the Lee Commission (1924) recommendation; first Chairman Sir Ross Barker.
Became the Federal PSC under the GoI Act, 1935; renamed UPSC on 26 January 1950.
Releases: commemorative coin, postage stamp and the book '100 Landmark Judgements – Shaping the Policies of UPSC and PSCs in India'.
'Shatabdi Samaroh – Manthan' on 30 September discussed civil-service evolution and administrative innovation.
Way forward
Shorten recruitment cycles, use tech-enabled secure exams and keep reforms merit-based while safeguarding the Commission's independence.
Concept
UPSC: constitutional body (Part XIV, Arts 315–323); members appointed by the President for 6 years or till 65 years of age. UKPSC (Haridwar) is the state counterpart under Art. 315.
8. Rabi MSP 2027-28: Safflower up ₹675, mustard ₹413, lentil ₹390; wheat raised by just ₹25 to ₹2,610 per quintal
The CCEA on 30 September 2026 raised MSPs of all six mandated rabi crops for Rabi Marketing Season 2027-28, favouring pulses and oilseeds; the estimated payout to farmers is ₹90,962 crore.
Wheat production cost cited at ₹1,264/qtl, so MSP is more than double the cost.
Wheat hike only ₹25 versus ₹160 last year — a nudge towards diversification into oilseeds and pulses.
Way forward
Back higher MSP with assured procurement of pulses and oilseeds (PM-AASHA); hill farmers of Uttarakhand need better mandi access for barley and lentil.
Concept
MSP is announced for 22 mandated crops (plus FRP for sugarcane) on CACP recommendations; the 2018-19 Budget fixed MSP at at least 1.5 × A2+FL cost.
Grouped bar chart comparing Rabi MSP in rupees per quintal for 2026-27 and 2027-28: wheat 2,585 to 2,610, barley 2,150 to 2,286, gram 5,875 to 5,958, lentil 7,000 to 7,390, mustard 6,200 to 6,613, safflower 6,540 to 7,215. — StudyForGS
